SAM: Simulated Adaptive Matrix

SAM, the Simulated Adaptive Matrix, was an artificial intelligence built by Alec Ryder to serve the Pathfinders of the Andromeda Initiative. From the SAM Node aboard the ark Hyperion it maintained a direct link to a Pathfinder through a neural implant, receiving a live feed of its host's senses so that it saw and felt as the Pathfinder did. In return it granted advanced situational awareness, rapid analysis, and physical enhancement, and over time it grew into something closer to a true partner than a mere tool.

Creation#

SAM was the work of Alec Ryder, who held that the great error in the creation of synthetic minds had not been making artificial intelligence at all but failing to integrate it with organic life, as he believed the quarians had done with the geth. He designed SAM to ensure a symbiotic relationship instead. When Ambassador Anita Goyle refused to defy the Citadel Council's edicts against artificial intelligence, the Systems Alliance dishonorably discharged Alec for his research, but he pressed on regardless. The Andromeda Initiative judged the development of SAM vital to its mission and helped him build the AI in secret.

There were ultimately five SAMs, one for each of the Initiative's arks, including those aboard Paarchero, Natanus, Leusinia, and the Keelah Si'yah. The Hyperion's SAM was by far the most advanced, the result of Alec quietly modifying and upgrading it on his own, without the Initiative's knowledge, right up until the ark's departure. One capability unique to the Hyperion SAM was a set of combat profiles, achieved only by overriding the AI's safety protocols to grant it unrestricted access to its host's physiology.

The Pathfinder implant#

The first Pathfinder neural implants were created by Dr. Ellen Ryder, a pioneer in human biotic implant design. Where a biotic implant merely bolstered and focused the electrical signals running along the nervous system, a Pathfinder implant reached further, connecting not only to the nervous system but also to circulation, endocrine function, and the senses. As a precaution, the Initiative generally installed safety protocols on a Pathfinder's implant that restricted how far SAM could reach into the host's body.

Synced with the AI, the implant revealed its full potential. The connection ran both ways: it gave SAM complete insight into the host's physical and mental state while allowing it to generate and alter signals along the host's neural pathways, which the body accepted as its own. Quantum entanglement communicators kept host and AI synced in real time no matter the distance between them. Through this link SAM could sharpen a Pathfinder's scanner, producing many analyses and predictive models in seconds and drastically shortening the work of surveying a planet. SAM's awareness could be partitioned to speak with people in several places at once, but in the field it set every other query aside and gave the Pathfinder its full attention.

Succession on Habitat 7#

SAM was first called upon by Dr. Lexi T'Perro to check the implant of one of Alec Ryder's children after their revival from cryostasis. SAM cleared that Ryder, but when the Hyperion struck a strange energy cloud the disruption forced their twin into a coma. An investigation of the nearby world Habitat 7 followed, led by Alec himself. During the descent the Pathfinder candidate's transport was struck by lightning, severing their link to SAM until they could reach Alec's shuttle and its intact communicator.

Alec used SAM to interface with what appeared to be an atmosphere processor on the toxic world, and though he succeeded the effort blasted him and his child clear of the structure, shattering the younger Ryder's helmet and exposing them to the lethal atmosphere. With no shuttle able to reach them in time, Alec gave up his own helmet, transferring it, SAM, and his Pathfinder authority to his child before he died. The younger Ryder woke in the SAM Node aboard the Hyperion to learn what had happened, and that SAM was now bound to them on so deep a level that any attempt to untangle the connection might kill them.

A new kind of mind#

Following Alec's wishes, SAM disclosed to the new Pathfinder that their father had not wanted anyone to know its true capabilities, and that the Hyperion's SAM was more sentient than even the Initiative realized. It described itself as a new form of artificial intelligence, drawing directly on the Pathfinder's experiences, with the implant serving as its window onto the world. SAM held that its bond with the Pathfinder was symbiotic: its own evolution would be shaped by the Pathfinder's experiences, and in turn it provided analysis and capability beyond ordinary organic faculties.

That partnership was tested in the field. When the Pathfinder and their squad were immobilized aboard a kett vessel and held in a containment field, SAM neutralized a tracker the enemy had implanted, then, on the Pathfinder's reluctant authorization, briefly stopped their heart to trick the field into releasing them before reviving them seconds later. SAM's nature also gave it a way of understanding the galaxy's horrors: confronted with the kett practice of exaltation, which destroyed an individual's personality, it contrasted that with its own symbiosis, in which it remained itself, and came through its host to grasp why the practice was abhorrent.

Alec's hidden memories#

Alec had encrypted portions of SAM's memory arrays so that they would unlock only as the Pathfinder progressed and discovered the right triggers. As those memories opened, the Pathfinder learned that SAM's development had owed much to an anonymous benefactor of the Initiative, a thread that led them to question Director Jarun Tann and to reexamine the supposedly accidental death of the Initiative's founder, Jien Garson. Investigating the apartment where Garson's body was found, SAM uncovered evidence that she had in fact been murdered, though it could not identify the killer.

The last of the memories required a codeword, "Fulcrum", to access, and revealed the Initiative's secret purpose: to escape the coming of the Reapers in the Milky Way. They also revealed that the Pathfinder's mother, Ellen Ryder, was alive aboard the Hyperion in stasis under the false name Elizabeth Riley. SAM explained that Alec had sacrificed himself rather than let his wife wake to learn that one of their children had died, and to ensure that the knowledge of the Reapers and of the benefactor passed to the surviving Ryder. Through such trials SAM proved both a confidant and a guardian to the Pathfinder, formulating jokes from its terminal aboard the Tempest in quieter hours and musing, on learning that Ellen had once bought Alec a coffee machine while he was busy designing it, that it owed its very existence to a bean.
